## Abstract The Mössbauer resonance absorption is measured in various silicates containing iron. The observed isomeric shifts are in accordance with the interpretation of WALKER. Even for Fe^3+^ ions, large quadrupole splittings are found. The analysis of the spectrum of tourmaline is similar to th
The broadening of the 14.41 keV Mossbauer line of "Fe due to diffusion of iron atoms in polycrystalline beryllium has been investigated in the temperature range 1123 to 1423K. The observed broadenings obey the Arrhenius law with activation energy 1.66( 10) eV, i.e.. lower than that obtained from th
